In Neo environment we can provide the query parameter in the application link "?saml2idp=trust store" to make the application use desired trust setting when accessing the HTML5 application.

What would be the approach in cloud foundry application ? The UAA implementation automatically gets the current active trust IDP, how can I manipulate the Cloud Foundry hosted app to use particular trust store IDP (similar to what you can achieve by "?saml2idp=" url parameter in Neo environment hosted applications)
